Kabukicho is interesting in that its got “red light” stuff but much more than that in terms of entertainment, food, drinks, etc. The big movie theater in the “Godzilla building” is me and the wife’s favorite since its probably the closest to where we live and the most recently built so good screens, sound and comfy seats. Shinjuku’s city hall building is also located in Kabukicho.
Here’s a few pictures of the area
Never been there but from what I understand the “food” is just to satisfy the place being licensed as a restaurant.
